Optimal siting of power emergency service station considering outage risk of loads

A model for the optimal siting of power emergency service stations is developed with the consideration of power outage risk of loads,which is determined by the power shortage,load type and outage probability in unit time. The model takes the minimum total risk of all loads as its objective and introduces the overtime penalty factor into the time constraint of emergency service response when it can not be satisfied in practical conditions. Floyd algorithm is applied to solve the optimization model. Case study shows that,because the proposed model considers the difference of power outage risk among loads,the practical larger power outage cost is avoided,which may occur if only the minimum response time is taken as its objective.
